Could Colorado See the Return of Grizzlies, Wolves and Wild Bison? Here’S How Montanans Coexist with Them Could Colorado see the return of grizzlies, wolves and wild bison? Here’s how Montanans coexist with them. Up north, grizzlies are roaming in places they haven’t been in decades and there are enough wolves that hunters are allowed to shoot five apiece Published on Aug 8, 2019 5:01AM MDT Environment Primary category in which blog post is published Jennifer Brown @jenbrowncolo KALISPELL, Montana — The latest grizzly bear killed by Montana officials was a relatively small, 278-pounder who ate 40 sheep and lambs in a two-week span, unfazed by four guard dogs and a range rider on a four-wheeler who tried to chase it away. The bear, euthanized July 19 outside of Great Falls, was the 20th grizzly so far this season killed by Montana Fish, Wildlife and Parks or hit by a car or train along the Northern Continental Divide. The region’s human-related grizzly deaths are on par with last year’s record-setting season, a result of a growing population of both bears and people. “We’ve got bears right now in areas where we haven’t seen them in decades,” said Dillon Tabish, a Kalispell-based education program manager for the state wildlife department. As Coloradans face questions about whether to reintroduce the grizzly — and fellow titan of the forest, the gray wolf — the state can look to its northwestern neighbors, where the native animals are making a comeback after decades on the brink of extinction. A recently filed lawsuit demands the U.S. Fish and Wildlife Service explore reintroducing grizzlies to Colorado, while a petition about to circulate in Colorado would put the question of wolf reintroduction on the November 2020 ballot. On their own, grizzlies have returned to the Bitterroot Mountains in Idaho and Montana, as well as the Rocky Mountain Front, where the Montana mountains meet the plains. They number close to 2,000 in the mountains of Wyoming, Montana, Idaho and Washington. And the gray wolf, with a population estimated at about 300 just more than a decade ago in Montana, has rebounded so dramatically that hunters there complain the wolves are decimating elk and deer populations. Montana now has a hunting season on the once-endangered species — six months long with a five-wolf bag limit. Wolves number about 850 in that state, and 315 were killed during the most recent hunting season. Still, irritated elk and deer hunters are packing the house when state wildlife officials come to town, protesting that wolves have hampered their ability to stock their freezers with wild game.

Steve Bullock this summer created an 18-member Grizzly Bear Advisory Council. The group of citizens, chosen from more than 150 applicants, is tasked with making recommendations about how to keep humans — and bears — safe in bear country. The panel comes a few months after a man teaching a friend to hunt was mauled by a grizzly near Columbia Falls in northwest Montana. Anders Broste told Montana Public Radio he fell on his back while trying to get away and the bear got on top of him and started biting and tearing his arm and leg. He survived because the griz ran away after pulling off his boot. Three years ago, in June 2016, U.S. Forest Service law enforcement officer Brad Treat was mauled to death by a grizzly bear, also in northwestern Montana, when he rounded a curve on his mountain bike and collided with the bear, which was startled and attacked him. Any effort to reintroduce large carnivores to areas where they haven’t lived in decades is met with fear — fear of human injury or death, and fear that a protected species could bring greater restrictions in logging, mining and access to public lands. “It’s really important to have the public invested and involved in the management,” Tabish said. “If you just force it upon people, it doesn’t end well. History has shown that recovery requires the public’s investment. You can’t just put grizzly bears on the landscape. You need to have public tolerance.” But fear of the grizzly, which can weigh more than 1,000 pounds, is part of the fascination. It’s one of the reasons millions of people drive to Glacier National Park every summer hoping to see one — from a distance. Hiking without bear spray, which only works within about 15 feet, is not recommended, and trailheads often are marked with a bright-red sign picturing a hump-backed, brown griz and an alert: “Do not approach or feed.” Would grizzlies move to Colorado on their own? It’s highly unlikely that grizzlies would return to Colorado on their own, crossing highways and moving across populated flatlands, said Andrea Santarsiere, a senior attorney for the Center for Biological Diversity. The group filed a lawsuit in June asking the U.S. Fish and Wildlife Service to initiate research regarding reintroduction of grizzlies to places they once roamed, including the San Juan Mountains of southwestern Colorado. The last grizzly documented there was in 1979, when an outfitter leading a hunting trip stabbed it to death with an arrow. “We are not proposing right now that we should introduce them tomorrow,” said Santarsiere, who lives in Idaho and spends weekends hiking in bear country, bear spray strapped to her backpack. “We’re not looking at dropping grizzly bears in Denver proper.” Grizzlies were listed as a threatened species in 1975 in the lower 48 states (Alaska and Canada have robust populations). A grizzly bear recovery plan identified six zones in the lower 48 states, places the bears still lived or had lived most recently: • The Northern Continental Divide, including Glacier National Park and northwest Montana, which now has an estimated 1,000 grizzlies • Yellowstone National Park and its surrounding area, with an estimated 700 to 800 grizzlies • The Cabinet-Yaak in extreme northwest Montana and Idaho, which has 50 to 60 bears • The Selkirk Mountains of northern Idaho and eastern Washington, with an estimated 50 to 80 bears • The Bitterroot Mountains, mostly in Idaho but also Montana, an area that is just starting to see evidence of the grizzly’s return • And the North Cascades of Washington, which officially has no bears (although there have been reported sightings) but is the subject of a reintroduction plan now seeking public comment One of the Denver Zoo’s two grizzly bears sits in Harmony Hill, the zoo’s new bear exhibit, on May 15, 2019. (Courtesy of Denver Zoo) Grizzlies once roamed from Alaska to Mexico, from the West Coast to the Great Plains, and numbered in the tens of thousands. Today, there are an estimated 2,000 in the lower 48 states, limited to those five, isolated zones. While the populations have increased significantly in recent years, exceeding the bar set by federal wildlife officials for some areas, “recovery is more than just reaching a certain numerical population,” Santarsiere said. The Center for Biological Diversity wants the grizzly populations to connect, not live in isolated areas, for the genetic health of the bears. Restoring native animals to the landscape for future generations On a recent July day, Wayne Kasworm, a U.S. Fish and Wildlife biologist and grizzly expert based in Libby, Montana, had crews in the woods measuring this summer’s huckleberry crops. It’s a decent season, which means the bears should have a good amount of food. Kasworm’s also got biologists collecting grizzly bear hair samples caught on tree branches as part of a genetic testing program to count the bears and see whether they are healthy. Several bears in the area are radio collared, so he can track their movements. A grizzly bear is spotted by a resident of northwest Montana. (Sally Costello, Special to The Colorado Sun) Natural migration is possible — he’s seen it happen with grizzlies moving down from Canada, and into the Bitterroot range in Idaho — but not as far of a trek as from Montana and Wyoming to Colorado. Healthy grizzly populations expand their range by small amounts each year — a chart showing their growing range looks like ripples in a pond. “I don’t see that happening in my lifetime,” Kasworm said. Young male grizzlies often roam far from their mothers when they set out on their own at about 2 years old, but female grizzlies typically stay on their mother’s range or adjacent to it, he said. “Obviously, you need both sexes to create a population.” Even human-led reintroduction is a slow process, he said. To supplement the grizzly population in the Cabinet Mountains of Idaho and Montana, Kasworm and team have transferred 22 animals since 1990 from the backcountry of the northern Contintental Divide. Federal proposals to reintroduce grizzlies to the North Cascades in Washington, as well as a reintroduction plan for the Bitterroots a decade ago that fizzled out, called for bringing a minimum of 20 animals to start. During a previous public comment period about the North Cascades proposal, those opposed to the reintroduction said federal officials should allow repopulation to happen naturally and spend tax dollars elsewhere. Others noted that if any grizzly left the designated recovery zone, authorities should return them deep into the mountains, and that ranchers should have permission to shoot bears if they threatened their livestock. Because grizzlies are a federally protected species, it’s illegal for ranchers to kill them.

  • Red Wolf Brochure
    U.S. Fish & Wildlife Service Endangered Red Wolves The U.S. Fish and Wildlife Service is reintroducing red wolves to prevent extinction of the species and to restore the ecosystems in which red wolves once occurred, as mandated by the Endangered Species Act of 1973. According to the Act, endangered and threatened species are of aesthetic, ecological, educational, historical, recreational, and scientific value to the nation and its people. On the Edge of Extinction The red wolf historically roamed as a top predator throughout the southeastern U.S. but today is one of the most endangered animals in the world. Aggressive predator control programs and clearing of forested habitat combined to cause impacts that brought the red wolf to the brink of extinction. By 1970, the entire population of red wolves was believed to be fewer than 100 animals confined to a small area of coastal Texas and Louisiana. In 1980, the red wolf was officially declared extinct in the wild, while only a small number of red wolves remained in captivity. During the 1970’s, the U.S. Fish and Wildlife Service established criteria which helped distinguish the red wolf species from other canids. From 1974 to 1980, the Service applied these criteria to find that only 17 red wolves were still living. Based on additional Greg Koch breeding studies, only 14 of these wolves were selected as founders to begin the red wolf captive breeding population. The captive breeding program is coordinated for the Service by the Point Defiance Zoo & Aquarium in Tacoma, Washington, with goals of conserving red wolf genetic diversity and providing red wolves for restoration to the wild.

  • Grizzly Bear Fact Sheet
    Identify Grizzly from Black Bears Grizzly bears typically weigh 100-200 kg (females) to 200-300 kg (males) which is slightly more than black bears. Grizzly bears have a shoulder hump, range in colour from blonde to black and may have silver or light- tipped guard hairs on their head, hump and back. A grizzly bear’s ears are rounded and appear smaller than the black bear, while the black bear has more pointed, noticeable ears and no shoulder hump. Grizzly bear claws are longer than those of black bears and may have a light-coloured stripe.

  • How People Should Respond When Encountering a Large Carnivore: Opinions of Wildlife Professionals Dy L a N E
    Human–Wildlife Conflicts 2(2):194–199, Fall 2008 How people should respond when encountering a large carnivore: opinions of wildlife professionals DYLA N E. BRO wn , 507 Silo Loop, Kinsey, Montana 59338, USA [email protected] MI C HAEL R. CO N OVER , Jack H. Berryman Institute, Department of Wildland Resources, Utah State University, Logan, Utah 84322-5230, USA Abstract: We conducted telephone surveys of wildlife professionals who work with large carnivores to ask their opinions about how people should respond to avoid being injured when confronted by a black bear (Ursus americana), grizzly bear (Ursus arctos), mountain lion (Puma concolor), or gray wolf (Canis lupus). The respondents agreed that the most appropriate response was to try to increase the distance between a person and the carnivore. In the event of an attack by a black bear, mountain lion, or wolf, most respondents said to fight back. Opinion was divided over the best response for an individual who was being attacked by a grizzly bear, but a slight majority of professionals said to fight back if the attack was predatory and be passive if the attack was defensive; however, respondents also noted that many victims would be unable to identify the bear’s motive. If a black bear came into camp, most respondents said that a person should aggressively encourage the bear to leave and to fight back against a bear that enters a tent at night, regardless of species. Respondents unanimously agreed that bear pepper-spray is effective in defending against an attack. While any encounter with a large carnivore can be fatal to the person involved, we believe that selecting the right course of action increases the odds that the victim can escape without injury.

  • The Effects of the Lake Trout Introduction in Yellowstone Lake on Populations Outside the Aquatic a Meta-Analytic Study
    Migrate, Mutate, or Die: The effects of the lake trout introduction in Yellowstone Lake on populations outside the aquatic A Meta-Analytic Study By Sarah Z. Gandhi-Besbes University of Colorado at Boulder A thesis submitted to the University of Colorado at Boulder in partial fulfilment of the requirements to receive Honours designation in Environmental Studies May 2016 Thesis Advisors: Alexander Cruz, Ecology and Evolutionary Biology, Committee Chair Dale Miller, Environmental Studies Andrew Martin, Ecology and Evolutionary Biology © 2016 by Sarah Z. Gandhi-Besbes All rights reserved i Abstract Yellowstone National Park is a relatively pristine ecosystem preserved through time. The Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri population, inhabiting shallower waters in Yellowstone Lake and spawning in its tributaries, has been declining primarily due to the introduction of a predatory fish. The lake trout Salvelinus namaycush, which rapidly grow to large sizes, feed on the Yellowstone cutthroat trout, breed and spawn in Yellowstone Lake, and dwell in deeper waters out of predatory reach. The Yellowstone cutthroat trout is relied upon both directly and indirectly by more than 40 species within Yellowstone National Park. The grizzly bear Ursus arctos horribilis, bald eagle Haliaeetus leucocephalus, and osprey Pandion halaetus all feed directly on the spawning fish. This study looks at how the declining Yellowstone cutthroat trout populations affect these predatory populations, and what their populations may look like should current trends continue into the year 2030. Conducting a meta-analysis and collecting primary data allowed for statistical projections predicting and comparing estimated future populations. The ecological change in Yellowstone Lake provides insight into how the concerns of one ecosystem affects multiple.

EXECUTIVE SUMMARY At the end of 2019, the wolf population in Wyoming remained above minimum delisting criteria; making 2019 the 18th consecutive year Wyoming has exceeded the numerical, distributional, and temporal delisting criteria established by the U.S. Fish and Wildlife Service. At least 311 wolves in ≥43 packs (including ≥22 breeding pairs) inhabited Wyoming on December 31, 2019. Of the total, there were ≥94 wolves and ≥8 packs (≥7 breeding pairs) in Yellowstone National Park, ≥16 wolves and ≥3 packs (1 breeding pair) in the Wind River Reservation, and ≥201 wolves and ≥32 packs (≥14 breeding pairs) in Wyoming outside Yellowstone National Park and the Wind River Reservation (WYO). In WYO, ≥175 wolves in ≥27 packs resided primarily in the Wolf Trophy Game Management Area where wolves are actively monitored and managed by the Wyoming Game and Fish Department and ≥26 wolves in ≥5 packs in areas where wolves are designated primarily as predatory animals and are not actively monitored. A total of 96 wolf mortalities were documented statewide in Wyoming in 2019: 92 in WYO, 3 in Yellowstone National Park, and 1 in the Wind River Reservation.

This butterfly is currently listed by the federal government as threatened and by the state as endangered. However, no critical habitat in I Washington has been designated under the Endangered Species Act (WDW 1993b). The Oregon silverspot is found only in habitats that support its larval host plant, western blue violet (Viola adunca). Such habitats include coastal salt-spray meadows and open fields. In Washington, potential habitat for the Oregon silverspot is limited to the coastal grasslands on the Long Beach peninsula near Loomis Lake (WDW 199313; WDW 1991).Adult butterflies are thought to rest and feed in adjacent open spruce/shoreline pine forest glades, where they are protected from wind and can feed on nectar available from a number of plant species.

  • Yellowstone Wolf Project: Annual Report, 1997
    Suggested citation: Smith, D.W. 1998. Yellowstone Wolf Project: Annual Report, 1997. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming, YCR-NR- 98-2. Yellowstone Wolf Project Annual Report 1997 Douglas W. Smith National Park Service Yellowstone Center for Resources Yellowstone National Park, Wyoming YCR-NR-98-2 BACKGROUND Although wolf packs once roamed from the Arctic tundra to Mexico, they were regarded as danger- ous predators, and gradual loss of habitat and deliberate extermination programs led to their demise throughout most of the United States. By 1926 when the National Park Service (NPS) ended its predator control efforts, Yellowstone had no wolf packs left. In the decades that followed, the importance of the wolf as part of a naturally functioning ecosystem came to be better understood, and the gray wolf (Canis lupus) was eventually listed as an endangered species in all of its traditional range except Alaska. NPS policy calls for restoring native species that have been eliminated as a result of human activity if adequate habitat exists to support them and the species can be managed so as not to pose a serious threat to people or property outside the park. Because of its size and the abundant prey that existed here, Yellowstone was an obvious choice as a place where wolf restoration would have a good chance of succeeding. The designated recovery area includes the entire Greater Yellowstone Area. The goal of the wolf restoration program is to maintain at least 10 breeding wolf pairs in Greater Yellowstone as it is for the other two recovery areas in central Idaho and northwestern Montana.
